Method of tow splicing

ABSTRACT

DISCLOSED IS A METHOD OF SPLICING THE TRAILING END OF A FIRST TOW OF THERMOPLASIC FIBERS TO THE LEADING END OF A SECOND TOW OF THERMOPLASTIC FIBERS COMPRISING FOLDING THE FIRST AND SECOND TOWS INTO A &#34;SIDE&#34; RELATIONSHIP AND HEATING BOTH TENSION TOWS IN A REGION WHICH IS SUBSTANTIALLY PERPENDICULAR TO THE LENGTH OF THE TOWS SO AS   TO THERMOPLASTICALLY SPLICE BOTH TENSION TOWS TOGETHER AND SEVER FROM THE REMAINDER OF THE TOWS THE PORTION OF BOTH TOWS FROM THE END OF THE TOWS TO THE HEATED REGION. CELLULOSE ACETATE FIBER IS A PARTICULARLY DESIRABLE FIBER FOR USE IN THIS INVENTION.

Int. Cl. B65h 69/02 US. Cl. 156-158 3 Sheets Drawing. 4 Pages Specification Disclosed is a method of splicing the trailing end of a first tow of thermoplastic fibers to the leading end of a second tow of thermoplastic fibers comprising folding the first and second tows into a side by side relationship and heating both tension tows in a region which is substantially perpendicular to the length of the tows so as to thermoplastically splice both tension tows together and sever from the remainder of the tows the portion of both tows from the end of the tows to the heated region. Cellulose acetate fiber is a particularly desirable fiber for use in this invention.
